IMPROVED QUARTZ-COMMINUTOR.

Specification forming part of Letters Patent No. 54,045, dated April 17, 1866.

To all whom it may concern:

Be it known that I, OWEN G. VARREN, of the city, county, and State of New York, have invented a newl and useful Improvement in the Apparatus for Triturating Ores in Vater; and I hereby declare that the following is a full and exact description thereof.

This invention is called Varrens dissolving apparatus, or VVarrens quartz comminutor.77

To enable others to make and use my invention, I proceed to explain it in detail, reference being had to the drawings hereunto annexed and making part of this specification.

Figure lis an end elevation of the tank 5 Fig. 2, asideelevation, Fi 3, avertical section Fig. 4,a birds-eye view Fig.5, adiagram section of the solid stock which holds the cylinders.

The same. letters refer to the same things in all the designs.

A is the tank; B, the base or casting, intended to be heavy and strong; C, the cylinders or rollers for crushing or comminutin g the ore; D, scrapers to prevent the ore packing at the bottom E, driving-pulley; F, the great pulley, onwhich is put a chain-band to turn the gang of rollers. It is on the solid rim upon each end of the horse-roller G, Fig. 5, that carries the six crushing-cylinders C. G, section ot the horse-roller; H, journal-boxes for the crushingcylinders O. These are circular on the periphery, and constitute the rim on which the band runs. Dovetailed into these are the Scrapers.

Upon a horse-frame or horse-roller, Gr, Fig.

5, I mount the crushing-cylinders C, which should Weigh at least ten tons each. They are simple cylinders of cast-iron made solid, with a journal at each end. Any number may be used, but six is the best number. Between the rollers C, I set scrapers I), which are simple liat bars of iron lying parallel with the cylinders, and just touch the surface on which the rollers C run. On the ends ot' the horseframe G are the pulleys F for a chain-band. This horse-frame G, carrying its six rollers, is set in a tank adapted to be heated by steampipes or otherwise. The bottom of the tank is seniicircular, and it should be high to hold much Water, orit may be one-third of a circle. At the top ot' the tank should be a shaft and pulleys,E, to turn the horse-trame, so that its cylinders may roll with their Weight upon the bottom (as anti-friction bushes roll Within their box) to comminute the ores..

For convenience there should be an elevator to deposit in the tank the granulated ore, and there should be sluices to supply Water and faucets to draw it oft' at different stages while washing the ore. Steam-pipes would heat the Water best.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

The horse-frame, carrying crushing-rollers C, Within a tank, in the manner substantially as above described, and for the purposes set forth.
